Just had a Dakota 3 position safety put on a 98 Mauser. It functions flawlessly until it's fired. The bolt is very stiff on lifting to extract and recock. I've check the external of the bolt and see no evidence of binding? I am using the original bolt body, firing pin,cocking piece, spring. extractor and collar. Would there be any interference between the cocking piece and the new shroud? Any other ideas?
